PORTABLE LIGHTING DEVICE.

Specification of Letters Patent.

Application filed April 29, 1918. Serial No. 231,478.

To all whom. it may concern.

Be it known that I, ROBERT DIXON, a citizen of the United States,residing at Armells, in the county of Fergus and State of Montana, haveinvented new and useful Improvements in Portable Lighting Devices, ofwhich the following is a specification.

This invention relates to ing devices. I

An object of the invention is to produce a device of this characterwherein a lamp and battery may be arranged in a suitable casing so thatthe same may be easily carried from place to place, the wires betweenthe lamp and battery being wound on a spring roller and readily unwoundtherefrom by a direct pull against the roller, so that the lamp may beused at any desired distance from the battery and casing, as isdesirable in automobiles and similar vehicles for locating trouble.

It is a further object of the invention to produce a device of thischaracter in which the roller is of insulating material, the coresthereof being of electric conducting material, and the bearings. for thecores being likewise of electric conducting material so that the wiresfrom the battery may be directly connected to either the bearings or theprojecting ends of the cores which provide trunnions that are journaledin the bearings, while the wires from a lamp are removably secured tothe cores, spring means being provided for winding the roller in onedirection, and clutch means being provided for controlling the springmeans.

With the above and other objects in view the improvement resides in theconstruction, combination and arrangement of parts set forth in thefollowing specification and falling within the scope of the appendedclaim.

In the drawings:

Figure 1 is a perspective view of the improvement, I

Fig. 2 is a similar view with the door of the casing open and the lamppartly withdrawn therefrom,

Fig. 3 is a horizontal sectional view approximately on the line 33 ofFig. 1,

Fig. 4 is a transverse sectional view ap proximately on the line 4-4 ofFig. 3,

Fig. 5 is a greatly enlarged sectional view on the line 5-5 of Fig. 4,

portable lightgig. 6 is a perspective view of the roller, an

Fig. 7 is a similar View of the bearings.

The casing 10, in the construction illustrated by the drawings, is of asubstantially rectangular formation, but it is to be understood that thesame may be of any desired shape and size, the casing, however,

being constructed of some suitable nonelectric conducting material. Theopen face of the casing is normally closed by a hinged door 11, suitablelatching means 12 being provided for locking the door on the casing.

In the casing, on the ends thereof, are secured oppositely disposedbearing members 13 which are of metal or of any other desired electricconducting material. In the bearings are journaled the trunnions 14 ofthe roller 15. The trunnions are of metal or of other suitable electricconducting ma terial and are formed with and provide the ends of cores16 and 1-7 which are centrally embedded in the roller for a considerabledistance but Which terminate a suitable distance away'from each other.The cores 16 and 17 are engaged by angular elements 18 which arethreaded and which, of course, are arranged in suitable openings in theroller. The elements 18, however, do not extend to the periphery of theroller, the outer ends of the same being received in pockets 19 formedin the roller. By reference to the drawings it will be noted that thethreaded members 18 of the cores 16 and 17 extend in opposite directionswith respect. to each other, and consequently the pockets 19 arearranged on the opposite sides of the roller 15. On each of the elements 18 is arranged a washer 20, and on each of the elements 18 isscrewed a nut 21. Between the washer 20 and the nut 21 of the respectiveelements 18 is arranged the wires 22 connected with the lamp 23, and itwill be apparent that when the roller it turned in its bearings thewires 22 will be wound therearound. It is also to be understood that thewires 22 are provided with a suitable coating of insulating material.

In the casing 10 is arranged a battery 24, the wires 25 and 26 therefrombeing directed to the respective bearings .13 and being attachedthereto, preferably by binding elements 27, and these binding elementsmay, if desired, be in the nature. of one of the screws employed forsecuring the hearings to the ends of the casing. The means for sup"porting the battery, illustrated by the drawings, comprises spring clips30 that are bent upon themselves to provide rounded portions 31 thatengage the. battery. One of the ends of each of the clips is straightand this straight end, indicated by the numeral 32 is secured to one ofthe walls of the casing 10.

The roller is influenced in one direction by a spring 28 and has one ofits ends provided with the usual clutcln elements 29 for controlling thespring, whereby when the roller is partly unwound, the same may be heldagainst further turning except. When a direct pull is exerted thereon.

From the above it is believed that the sini plici-ty and advantages ofthe construction will be apparent, it being noted that the de vice is ofa compact nature and it may be readily conveyed from place to place andcarried in the pocket of the user. It will be also apparent that thewires 22 may be of any desired length, so that the lamp '23 a may beused a considerable distance away from the casing. it is to beunderstood, and

as illustrated by the drawings. that the. lamp is controlled by asuitable switch which is indicated by the numeral 30.

"What I claim .is

In a portable lighting device, a substani tially rectangular casinghaving an open top a hinged door therefor and latching means forsecuring the door closed on the casing, bearings of electric conduct ngmaterial on the ends of the casing, a spring influenced roller havingtrunnions received in the bearings. said trunnions being in the natureof electric conductors and extending centrally in the roller from theopposite ends thereof and terminating an approximately equal distanceaway from the center of the said roller. oppositely extending angularlydisposed binding posts on each of the trunnions adjacent to the innerends thereof, said binding posts having their outer ends received inpockets in the roller, an electric conducting wire connected with eachof the binding posts and a lamp connected with said wires, spring clipssecured to one of the sides in the casing. a

battery supported by said clips, and electric conductors between thepoles of the battery and the electric conducting bearings for therollers. 4
